Wavelength = speed / frequency
(345 m/s) / (20,000 Hz) = 0.017 m
The distance is 28 meters, and the displacement is -4.
For the distance it would be 12 + 16 = 28.
For the displacement it would be 12 - 16 = -4.
would really appreciate a brainliest! Hope this helped!
Answer:
More force
Explanation:
Pressure and force are related by the equation:

where
p is the pressure
F is the force
A is the area
We can re-arrange the equation as

In this problem, the pressure is kept the same (p' = p) while the area is increased. As we can see from the previous equation, the force applied is directly proportional to the area: therefore, a greater area means also a greater force.
- Total displacement=825m
- Total Time=118s
Average Velocity=Total Displacement/Total Time
